Tomatina Festival 2010, Spain

La Tomatina is a food fight festival held on the last Wednesday of August each year in the town of Buñol in the Valencia region of Spain. Tens of metric tons of over-ripe tomatoes are thrown at each other in the streets during this day. The week-long festival features music, parades, dancing, and fireworks among other things. On the night before, participants of the festival compete in a paella cooking contest. This festival started in a casual way in 1945, but wasn't officially recognized until 1952.
